AUTOMOBILE-RADITOR ATTCHMENT.

Application filed Getober 23, 1918.

To @El 'wimmelt may concern.;

Be it known that l, flosrrir J. CAVA- Niinorr, a citizen. of the United States, residing at Los Aangeles, in the county of Los angeles, State of California, have invented certain new and useful lrnprovernents in Antonioliile-ladiator Attachments; and l do hereby declare the following to be a full, clear, and exact description of the invention,

l0 such as will enable others skilled in the art to which it appertains to maire and use the same.

/ This invention relates to new and useful improvements in water cooling systems to' automobile engines, and articular-ly to an attachment for the radiator'.

@ne object of the present inventionis to provide a novel and improved device which is arranged to be applied to the radiator in 2e place of the ordinary cap, for the purpose 'of preventing escape of water when traveling over rough and uneven ground.

Another objeet is to provide a device of this Character which will prevent the water g5 from ,f ettingtoov hot and which will readily permit the escape of any steam arising,r from the water in the radiator.

Other objeetsv and advantages will be apparent from the following description 3@ when taken in connection with the aecom- 'panying drawing.

ln the drawing:

Figure l is an elevation of the device ap plied to an automobile radiator.

Fig. 2 is a vertieal sectional View taken on the line 2-2 of Fig. 1, slightly enlarged.

Fig'. is a horizontal sectional View taken Fig.

a Vertical sectional View taken en on the line lf-4r or" Fig. 2.

Referring particularly to the accompanying drawing, l0 represents a portion of an automobile radiator and 11 the lilling tube thereof, said tube being externally threaded,

lo as shown.

A casing l2 is provided with an internally threaded lower end 13 for engagement on the said filling tube 11 of the radiator. At a point, approximately midway of the height of the casing, there is formed a horizontal partition wall 1i having a central opening 15 formed with upwardly tapering walls, asshown. Fo",med vertically through the partition, at one side of the opening, is

an opening 16, and disposed through this Specification of Letters Fatent.

Patented i Serial No. 259.318.

opening:r is the lower end of a lient pipe or goose-neck 17, the other end being' directed downwardly toward the center oi tlie'opening 16. Adjusting nuts 1S and 19 are threadedly engaged on the lower portion of the goose-neck, above and below the wall 1+i, as shown in the drawing. These nuts are so adjusted that the pipe 17 will stay firmly in place when adjusted iu opening1 16, whereby steam can escape upwardly through said pipe. At a point in the wall 14, diametrieally opposite to the opening 3.6, there is formed another opening 15:3. and. disposed upwardly through this opening' is the vertical leg` 19', of an l..shaped ineinser 20. The horizontal portion of this member 20 extends transversely beneath the Central opening 15, and carried by said portion is a vertical stem 21 which extends up wardly through the center of the opening 15. Slidably disposed on this stern 21 is an upwardly tapering valve body 22, the

upper end of which is formed with an 11pwardly extending projection Q3 which is arranged to nearly engage in the downwardly turned end of the pipe 17, as said valve rises by the upward pressure of water in the -tilling tube. An aluminum band 2e is secured around the outer faoe o' the valve 22 for engagement with the tapered wall ol' the oper-ling` 15. il. retaining,` nut .25 is engaged on the upper end of the leg' 19 to hold. the ifshaped member -in proper ad. justed position. Hinged to the upper open iid oi? the easing is a cover 36, the intermediate portion being open as shown at 27'. A latch 28, cooperating with the oasing, is carried by the other side oi2 'the Cover to hold the same in closed position.

When traveling over rough or uneven ground the water in the 'radiator splashes upwardly and is wasted. Also, hy reason of the r'aet that the steam inthe water is confined within the radiator, the water becornes heated more quickly and retains the heat for a longer period, thus greatly impairing` the. working of theA engine, and preventing the proper cooling of the water in the jaelret. By reason of the fact that the cover is open, and the valve normally open, the heat can escape upwardly throughv the opening 15, and through the pipe 17, thus causing a more rapid radiation and coolingl of the water. This will greatly aid in keeping the engine cylinders at the proper temgina peinture, and add to the efliciency of' the engine. Ae the water in the radiator `splashw upwardly it strikes the lower side i" the valve and lii'ts the saine into engagenient with the seat in the opening l5, thus preventing an)v escape of water, while at the the saine time the projection on the faire nearly' engages the goose-1ieck pipe and permits an)T steam to pass quickly through the goose-neck' pipe as will be readiljY umlerstood.

what is claimed is:

l'. iin atiachnient for an autoniohile radiitoi' including a asing :ii-ranged for engagement with the filling tube of a radiator, a floating valve within the casing arranged to he seated hy splashing water in the radiator, and a steam escape means adjacent the valve.

2. An attachment for an automobile radi aiior including a casing arranged to be engaged with the filling tube of the radiator, a vertical guide mounted in the casing, a valve seat in" Lthe caeing, a floating valve mounted to slide on the guide and engage said neat, and a steam escape pipe located adjacentthe Valve seat to permit escape of steam when the Valie is engaged with the seat.

3. An attachment for a radiator filling tube of an automobile including a casing, a horizontal wall in the casing having a central opening forming a Valve seat, a member mounted in the casing and having a stem extending upwardly through .said opening, a valve slidable 0n the stem and arranged to engage said seat to preyent escape of Water from the radiator, said wall having an opening adjacent the central opening, a bent steam escape pipe disposed for vertical adjustment through the lastnalncd opening, the valve having a Vertical projection arranged to enter but not close the upper end of the bent pipe, whereby steam will escape fromthe radiator through said pipe when the valve is engaged on its seat.

In testimony whereof, I aix my signa ture, in the presence of two witnesses.
